NATIONAL WEATHER SERVICE WICHITA KS
356 PM CDT TUE JUL 28 2015

.SYNOPSIS...
ISSUED AT 355 PM CDT TUE JUL 28 2015

THIS AFTERNOON A STRONG COLD FRONT EXTENDED FROM THE IA/NEBRASKA
BORDER TO BETWEEN K9K7 & KRSL...TO THE TX PANHANDLE. SE OF THE
BOUNDARY THE AXIS OF GREATEST COMPRESSIONAL HEATING WAS OCCURRING
FROM BETWEEN KSLN & KMHK TO ALONG & JUST W OF I-135/I-35 WHERE
TEMPERATURES HAD HIT AROUND 100F. THE MOST HUMID WEATHER RESIDED
E & SE OF THE TURNPIKE WHERE DEWPOINTS WERE BETWEEN 70 & 75.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 355 PM CDT TUE JUL 28 2015

THIS EVENING:
WITH HEAT INDICES HITTING ~105F IN MOST OF THE ADVISORY AREA THERE
WILL BE NO CHANGES TO THE INHERITED HEAT ADVISORYWHICH WILL REMAIN
IN EFFECT UNTIL 8 PM.

TONIGHT-WED NIGHT:
THE STAR OF THE SHOW IS THE AFORE-MENTIONED COLD FRONT. A CYCLONE
IS CENTERED OVER EXTREME SE SASKATCHEWAN. THE CYCLONE IS STILL
SCHEDULED TO STRENGTHEN FURTHER AS IT MOVES E/NE ACROSS EXTREME
SOUTHERN MANITOBA TONIGHT...THEN ACROSS NORTHERN ONTARIO ON WED.
THE CYCLONE SHOULD PROVIDE ENOUGH KICK TO FORCE THE FRONT TOWARD
THE TURNPIKE TONIGHT. THUNDERSTORMS WILL ERUPT ALONG THE BOUNDARY
WHICH WOULD ALSO PLAY A ROLE IN FORCING THE FRONT SE. GREATEST
THUNDERSTORM POTENTIAL WILL NO DOUBT REFLECT FRONTAL POSITIONING
I.E. FROM NORTHEAST KS...THRU CENTRAL KS TO THE OK/TX PANHANDLES
FOR MOST OF TONIGHT. WITH A SHARPENING MID-UPPER RIDGE PUNCHING
DUE N ACROSS QUEBEC THE CYCLONE CROSSING ONTARIO SHOULD OCCLUDE
WED NIGHT & DRIFT N OVER SOUTHERN HUDSON BAY. THE COLD FRONT WOULD
DECELERATE AS IT APPROACHES THE KS/OK BORDER EARLY WED MORNING.
THE FRONT SHOULD STALL IN AN ALMOST E-W MANNER THRU CENTRAL OK. AS
SUCH THE GREATEST THUNDERSTORM CHANCES WOULD GET SHUNTED TO THE SW
OF KICT COUNTRY (MORE SPECIFICALLY THE PANHANDLES & SOUTHWEST KS).
WITH LOWER-DECK CONVERGENCE DIMINISHING ACROSS MOST OF KS EARLY
WED MORNING THUNDERSTORM CHANCES WOULD DIMINISH LATE TONIGHT. WED
AS EXPECTED WON`T BE NEARLY AS WARM WITH HIGHS RANGING FROM THE
LWOER 80S IN CENTRAL KS TO THE LOWER 90S ALONG THE OK BORDER AS
WEAK HIGH PRESSURE GLIDES E/SE ACROSS THE NEBRASKA/KS BORDER.

THU-FRI:
WITH THE SURFACE HIGH DRIFTING TOWARD THE KS/MO BORDER ON THU S/SE
FLOW WOULD ENSUE WITH THE LOWER-DECK MOISTURE AXIS EXTENDING FROM
W TX TO ACROSS THE WESTERN HALF OF KS. AS SUCH GREATEST CHANCES OF
THUNDERSTORMS WOULD BE ALONG THE WESTERN THIRD OF THE FORECAST
AREA.

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 355 PM CDT TUE JUL 28 2015

THIS WEEKEND:
PREDOMINANTLY NICE WEATHER IS SLATED AS A MASSIVE MID-UPPER RIDGE
SPREADS FROM THE DESERT SW ACROSS THE CENTRAL ROCKIES.

NEXT WEEK:
SCATTERED THUNDERSTORMS REMAIN POSSIBLE AS THE WESTERN RIDGE
SPREADING N COMBINES WITH INTENSE LOW PRESSURE OVER ONTARIO &
QUEBEC TO PRODUCE A NW FLOW REGIME.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1127 AM CDT TUE JUL 28 2015

COLD FRONT STRETCHING FROM EASTERN NEBRASKA TO NORTHWEST KANSAS AT
MIDDAY...IS PROGGED TO REACH CENTRAL/SOUTHWEST KS BY EARLY
EVENING. THE FRONT WILL THEN PUSH INTO FAR NORTHERN OKLAHOMA
DURING WEDNESDAY. LOW-LEVEL CONVERGENCE AND STRONG INSOLATION
ALONG THE FRONT SHOULD EVENTUALLY ALLOW...CONVECTIVE UPDRAFTS TO
DEEPEN AND PENETRATE THE VERY WARM AIR ALOFT TOWARD EVENING.
ISOLATED TO WIDELY SCATTERED STORMS SHOULD AFFECT CENTRAL/SOUTH
CENTRAL KANSAS THIS EVENING...BEFORE WEAKENING LATE TONIGHT.
STRONG/VARIABLE WIND GUSTS AND BRIEF DOWNPOURS WITH REDUCTIONS IN
VISIBILITY ARE THE MAIN THREATS WITH THESE STORMS. WINDS WILL
SHIFT TO NORTHERLY BEHIND THE FRONT.
